Is it possible that we keep on increasing the number of turns of coil but the magnetic field strength remains constant?

Is it possible that we keep on increasing the number of turns of coil but the magnetic field strength remains constant?

Increasing the number of turns increases the magnetic field if the current remains constant. In your situation, you are postulating (implicitly) that the applied voltage is constant, and that the current is reduced.

Does angle affect magnetic field?

Figure 1: The magnitude of the force exerted by a magnetic field upon a moving positively charged particle depends upon the angle, θ , between the particle’s velocity, v, and the magnetic field B.

What does increasing the number of coils do?

You can add more coils on top of the first row, and this just adds more field strength. In technical terms, every coil of wire increases the “magnetic flux density” (strength) of your magnet. The magnetic field on the outside of the coil resembles a bar magnet.

What happens when you spin the coil in the other direction?

Once moving, the coil can continue to spin until the battery is dead. The reason that the magnet only spins in one direction is because spinning in the wrong direction will not cause the magnetic fields to repel each other, but attract.

In which direction does the magnetic field in the center of the coil point?

The standard right hand grip rule can be modified to predict the direction of the magnetic field. If the right hand fingers curl round the coil in the direction of the current, then the thumb points in the direction of the magnetic field down the centre of the coil.

What is the relationship between the current in the coil and the magnetic field?

The changing magnetic field caused by the material’s motion induces a current in the coil of wire proportional to the change in field. If a 0 is represented, the magnetic field does not change between the two domains of a bit, so no current is induced as the magnetic material passes the coil.

How magnetic field is produced in a coil?

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The small magnetic field caused by the current in each coil add together to make a stronger overall magnetic field.

How does the number of coils affect the magnetic field?

As the number of turns increases the number of paper clips held increase. This means that the strength of the magnet increases with increasing number of turns in the coil. We can say that, the strength of the electromagnet is directly proportional to the number of turns in the coil.

Why does the coil rotate continuously?

The coil of wire is mounted in the gap between the two magnets. The split rings make electrical contact with the coil and reverse the current every half turn. When an electric current flows through the coil, a force is exerted on the coil, causing it to spin.
